Institutions submit the number of majors by CIP (Classification of Instructional Programs) code. Those codes come in three different levels of specificity. At the highest level, the two-digit codes describe groups of majors. Code 27 includes all Mathematics and Statistics majors. The four subcodes (4 digits) include Mathematics (27.01), Applied Mathematics (27.02), Statistics (27.03), and Math and Stats, Other (27.04). Each of those is further broken down into 6-digit codes. 

 

A student receiving an applied mathematics degree would be included in the numbers reported for 27.02, as well as the overall two-digit category (27). 

 

Two graphs show data for all Mathematics and Statistics majors (code 27), first by state and then by Carnegie classification. They are labeled “Math/Stat Majors.” Two additional graphs showing data for the subset of those graduates who were listed as Mathematics majors (code 27.01), labeled as “Math Majors.” Those are again shown twice, once by state and once by Carnegie classification. Some schools show exactly the same numbers for both. Others, especially those with substantial numbers of statistics or applied math majors, show large differences. 

 

To arrive at the “Average % of Math Majors”, the percentage of math majors was calculated for each year from 2020 through 2023, then those four percentages were averaged. Thus when you mouse over an individual institution, the average will not be the same as the ratio of the last two pieces of data (which are only for 2023).

​

Note that to spread out the data, all graphs are shown on a log scale.
